The Library at Mount Char by Scott Hawkins

The story starts with a girl in a bloody dress walking down a dark highway and only gets stranger from there. The girl, after being orphaned at a young age, was taken in by a mysterious figure known only as Father. He trains her to become a Librarian of Languages in his odd library. This book takes all the elements of a fantasy novel and turns them on their head. Wherever you think this story is going, you're wrong. —Ivy
